[0022]

[Table 1]

Examples of the organic material include marine residues, insects, animals, coffee grounds, straw, rice hulls, rice straw, tea grounds, edible waste oil, and seed coats of beans such as soybeans, red beans, and peanuts. , Bark, excrement of livestock and poultry, various organic substances such as microorganisms that ate these seafood residues and the like, and mixtures of appropriate combinations thereof, among these,
Mixtures of marine residues and coffee grounds are preferred. In this case, the mixing ratio of the marine residue and the coffee cake is desirably about 7: 3 by weight.

The organic material may be used in a raw state containing moisture of about several tens% of the total weight. Fermentation is carried out by adding a predetermined ratio of thermophilic inoculum to this organic material and heating it by self-fermentation heat or a heater under aerobic conditions such as stirring under an air atmosphere.
What is necessary is just to carry out at 90 degreeC. Here, when the temperature is raised to 50 to 90 ° C. by irradiation with far infrared rays, there is an advantage that the temperature can be raised in a shorter time.

Since the water content of the mixture decreases as the fermentation progresses, the fermentation may be continued for several hours to several tens of hours until the water content becomes about 20% by weight or less to immobilize the thermophilic yellow-colored inoculum. . At this time, since a distillate is generated, it is desirable to collect the distillate separately. How to use this distillate will be described later.

As described above, when fermenting general microorganisms in a severe high-temperature environment, only the thermophilic Sorbus inoculum proliferates actively. Therefore, stable heat-resistant enzymes and chaperonin derived from the thermophilic Sorbus inoculum are used. There is an advantage that a powdery feed additive containing a large amount of an antioxidant functional component having excellent properties and sustainability can be produced. In addition, since fermentation is performed at a relatively high temperature of 50 to 90 ° C., there is an advantage that the moisture content of the mixture can be reduced to about 20% by weight or less in a short time to immobilize thermophilic yellowtail.

The obtained powdery feed additives include:
Since the thermophilic yellowtail seed is immobilized, a part or all of this feed additive and the above-mentioned organic material are mixed at a predetermined ratio, and fermented in the same manner as described above. A powdery feed additive can be produced without additional addition. In this case, the mixing ratio of the feed additive and the organic material is preferably about 7 to 3 by weight. Further, if this operation is repeated, there is an advantage that a powdery feed additive can be continuously produced without adding a thermophilic yellowtail inoculum.

Here, when at least a marine residue is used as the organic material, the activity of the thermophilic inoculum becomes higher due to the high-quality antioxidant components and minerals contained therein. Therefore, 50-90 depending on the heat of in-house fermentation
There is an advantage that the fermentation can be continued for a long time while the temperature is raised to ° C., and a heat-resistant enzyme derived from a thermophilic yellowtail inoculum or an antioxidant functional component such as chaperonin can be mass-produced. Examples of such marine product residues include edible portions of marine products such as shrimps, crabs, and fish, except for edible portions, or shrimp, small crab, and small fish that are not suitable for edible use. .

Further, if fermentation is carried out for a predetermined time or more, heat,
Alternatively, there is an advantage that harmful components such as environmental hormones such as dioxin, pathogenic bacteria, and pathogenic viruses can be decomposed by the thermophilic Sorbus inoculum or a thermophilic bacterium generated by mutation from the thermophilic Sorbus inoculum. In addition, when a mutation occurs in the thermophilic yellowtail, a novel thermophilic bacterium having these resolutions, which has been stored (biosensor) using environmental hormones, pathogenic bacteria, pathogenic viruses, etc. as food, can be cultured.

The feed additive thus produced is
As described above, it contains a large amount of an antioxidant functional component excellent in stability and persistence, such as a thermostable enzyme derived from a thermophilic Sorbus inoculum and chaperonin. The activity of the thermostable enzyme at room temperature is as long as about one year, while the enzyme derived from room temperature bacteria is within one week. The thermostable enzyme is not inactivated by an organic solvent such as ethanol.
Here, the chaperonin is a protein that helps the enzyme to exhibit a stable activity by retaining the structure of the enzyme and the like, but the chaperonin derived from a normal temperature bacterium is ATP (adenosine-5′-). In contrast to the necessity of the energy of triphosphoric acid, chaperonin derived from a thermophilic mirophilic inoculum has the property of working without the energy of ATP. For this reason, the chaperonin derived from the thermophilic mirophorus inoculum can prevent denaturation of the heat-resistant enzyme and other various enzymes in various environments, and can help its function.

From this fact, if a feed additive containing a large amount of an antioxidant functional component such as the above-mentioned heat-resistant enzyme or chaperonin is added to the feed, the livestock taking the feed can be healthy, The excrement no longer smells bad. Therefore, healthy livestock can be bred in a favorable environment. This is because antioxidant functional components prevent denaturation of digestive and degrading enzymes in the body of livestock and stabilize their functions, thereby improving digestion and absorption and promoting nutrient supplementation efficiently. It is considered to be. This idea could be applied to the human diet as a new nutritional perspective.

It should be noted that the feed additive may be added at a ratio of about several percent (weight ratio) to various conventionally known feeds. In addition, the livestock to which the feed containing the feed additive is fed is not particularly limited, and includes, for example, livestock such as dairy cows, beef cattle, horses, sheep, goats, pigs, and laying hens, broilers, and the like. Poultry and the like.

Thus, there is an advantage that safe livestock products and the like can be produced from healthy livestock. For example, in milk or the like milked from dairy cows, the concentration of steroid hormones such as glucocorticoids, which have an adverse effect on the human body, such as induction of diabetes and suppression of immune function, can be reduced. Also, safe beef, pork, chicken eggs, chicken and the like can be produced from beef cattle and the like.

In the method for producing a liquid feed additive according to the second embodiment, the powdery feed additive produced in the first embodiment is added to water and cultured at 30 to 70 ° C. under aerobic conditions. Is what you do.

The feed additive was added at a rate of 100
About 1 L is appropriate for L. Also in this case, as in the first embodiment, the fermentation is performed by adding a predetermined ratio of feed additive to water, and heating under aerobic conditions such as stirring in an air atmosphere or the like, by self-fermentation heat of a thermophilic yellowtail seed or a heater. The heating may be performed at 30 to 70 ° C. by heating. Further, when the temperature is raised to 30 to 70 ° C. by irradiation with far infrared rays, there is an advantage that the temperature can be raised in a shorter time.

When cultivated as described above, the thermophilic yellowtail inoculum contained in the feed additive proliferates actively, so that a large amount of antioxidant functional components such as heat-resistant enzymes and chaperonin derived from this thermophilic yellowtail inoculum. There is an advantage that a liquid feed additive can be produced.

Here, in the case where a distillate collected during the production of the feed additive is used instead of water, the distillate contains an antioxidant functional component derived from a thermophilic yellowtail inoculum. In addition, since the powdery feed additive is easily dissolved or adapted, there is an advantage that it can be cultured more efficiently.

If the cells are cultured for a predetermined period of time or longer, as in the first embodiment, environmental hormones such as dioxin may be produced by heat or thermophilic S. var. There is an advantage that harmful components such as pathogenic bacteria and pathogenic viruses can be decomposed. In addition, when a mutation occurs in the thermophilic yellowtail, a novel thermophilic bacterium having these resolutions, which has been stored (biosensor) using environmental hormones, pathogenic bacteria, pathogenic viruses, etc. as food, can be cultured.

The liquid feed additive produced in this manner has the same effect as the powdered feed additive, and
Since it is liquid, there is an advantage that it can be easily diluted and can be immersed or sprayed when it is mixed with a feed. In addition, when diluting the liquid feed additive, it may be diluted at an appropriate magnification of about several times to about 100 times (volume) depending on the use and the like.

A feed containing at least one of the feed additive and the liquid feed additive at a predetermined ratio is supplied to livestock 1 such as dairy cows.

Since the livestock 1 becomes healthy after a predetermined period from the start of the feeding, excrement that does not emit a bad odor (deodorization) is excreted, and the animal is bred in a favorable environment to reduce stress. . Therefore, if such high-quality manure is used, a high-quality organic fertilizer (compost) can be manufactured.

Specifically, the excrement of livestock 1 is added to the above-mentioned feed additive, and is subjected to aerobic conditions at 50 to 90 ° C. by a high-temperature fermenter (composting system) 5 or the like in the same manner as in the first embodiment. If fermentation is performed, powdery organic fertilizers containing many antioxidant functional components such as thermostable enzymes and chaperonins can be produced for several hours to several tens of Obtained in a short period of time.

Since this organic fertilizer contains a large amount of antioxidant functional components derived from thermophilic yellowtail, it is possible to prepare a habitat for microorganisms in the soil to be fertilized. Therefore, there is an advantage that it is safe and has an excellent fertilizer effect.
In addition, since it exhibits an antibacterial and lytic effect also against Fusarium spp. Which is a plant pathogen, there is an advantage that it can be fertilized as a pesticide-free fertilizer that does not require pesticides. Furthermore, since it is weakly alkaline, there is an advantage that acidification of the soil due to acid rain or the like can be prevented.

If such an organic fertilizer is applied to the soil 2 and the forage crop 3 such as grass is cultivated on the soil 2, there is an advantage that a safe forage crop 3 can be obtained efficiently. Therefore, since the feed obtained from the feed crop 3 is also safe, if it is used as feed for the livestock 1, there is an advantage that safe livestock 1 can be produced. Further, if the feed is mixed with the feed additive or the liquid feed additive and fed, the livestock 1 becomes healthier and the recycling cycle as shown in FIG. 1 can be formed. There is also.

The forage crops 3 include grasses such as orchardgrass and alfalfa that are used for grazing or harvesting, for example, wild grasses, forage crops, root crops,
Rice, corn, barley, oat, rye, millet, millet, millet, soybean, and the like.

Further, this organic fertilizer is added to water or the above-mentioned distillate in the same manner as in the second embodiment together with or instead of the above powdery organic fertilizer, and is added under aerobic conditions at 30 to 70 ° C.
May be used. In this case, it has the same effect as the powdered organic fertilizer, and is liquid, so that it can be easily diluted, irrigated,
There is an advantage that spraying and foliar spraying can be easily performed. When no feed is manufactured, these powdery organic fertilizers and liquid organic fertilizers may be used for crops other than the feed crop 3.
